Question

find the length of rectangle.whose perimeter is
200 cm and Breadth is 23cm.​

Answer 1

Answer:

A/q

p=200cm

b = 23cm

P = 2×(l+b)

200cm = 2×(l+23cm)

200cm= 2×l+46cm

2l = 200-46

2l= 154cm

l = 154÷2

l= 77cm

Length = 77cm

Answer 2

Answer:

77 cm

Step-by-step explanation:

Given,

Perimeter of a rectangle = 200 cm

Breadth of the rectangle = 23 cm

Therefore, by the problem,

=> 2(l+b) = 200 cm

=> 2(l+23) = 200

$= > l + 23 = \frac{200}{2}$

=> l + 23 = 100

=> l = 100 - 23

=> l = 77

Hence, the required length of the rectangle is 77 cm(Ans)
